First, don't reply to this post with anything that a criminal may find helpful in disabling your security system. I'm sure if my nieghbor got curious about the CK5.com sticker on my truck and stumbled across my posts, he may be able to tell more about me than I want, especially security info... So, with that dis-claimed: What're your opinions on home security systems? What kind do you have or want, and what features would you incorporate into one if you were designing it (aside from firearms and explosives)? If you wanted to circumvent a system, what would you try? I have a great opportunity to install new wiring and sensors for a security system, while rewiring just about my entire house, and breaking open walls, etc. I'm planning on designing some very non-standard features and fault tolerant-redundancies, but odds are I'm only doing this once, so I want to get as many ideas as possible right now. My objective is to have a system that will function 90% to alert us to and monitor an intuder, and 10% to deter/defend against intrusion.
